For anything beyond that, a recording would be nice if you can get one that shows the problem. If OBS does not pick it up, you might need an external recorder.
One guess is that you're using the internal audio hardware, which sits in the same electrically noisy box as everything else. Because everything else is digital, it's practically immune to all that noise, but the "last mile" audio path to your speakers or headphones is analog, and therefore *not* immune. So you're actually listening to your GPU and whatever else is active, in the extreme low-frequency ("sub bass", if you will) range compared to what those things are actually doing. (mid-to-high MHz and low GHz, compared to audio's low kHz tops)
To fix that, if it really is the problem, get a (good!) USB sound card. Get the analog part outside of the noisy box by some distance (a standard USB cord is more than plenty), and into its own box that is actually designed specifically to do that one job well. Don't just sort by price and pick the cheapest plastic cube that has USB and 'phone connectors, as those tend to use the same lousy chip that is designed to match the noisy box that it was originally meant to live in. Get something good instead, with some real engineering behind it.
